USAGE SUGGESTIONS

1. SCOPE OF APPLICATION FOR INSTALLATION
This fireproof grille is suitable for areas such as indoor walls, door frames, air ducts, and ceilings where both ventilation and fire protection are required; it ensures daily air circulation and can effectively close off in the event of a fire.
2. REGULAR INSPECTION REQUIREMENTS
The grille housing, installation and fixation status, and the integrity of the plastic casing need to be checked regularly; if any damage to the plastic casing or exposed expanded material is found, it should be replaced promptly to ensure fire protection performance meets the standards.
3. TRANSPORTATION PACKAGING SPECIFICATIONS
The product is first sealed in a plastic bag, then placed in a shockproof and moisture-proof hard carton; foam, bubble pads, and other cushioning materials are placed inside the carton to prevent damage during transportation; the packaging must have moisture-proof and dust-proof properties to prevent water and dust from affecting the product.
4. STORAGE REQUIREMENTS
Store in a cool, dry place indoors, avoid contact with chemicals, and prevent high temperatures and humidity from compromising fire-resistant properties; recommended storage temperature is 5℃-30℃, with humidity ≤65%; items should be stacked evenly to avoid excessive height that could cause damage to plastic casings or expanded materials, and the stacking height is recommended not to exceed 1.5 meters.
